BOTH TOP CAM PULLYS MEET JUST ABOUT THE MIDDLE. LEFT PULLY AT 3 O CLOCK POSITION SHOULD HAVE "IN" FOR INLET, RIGHT PULLY AT 9 O CLOK POSITION, WILL BE MARKED EX FOR EXHAUST, AT THE SIDE OF THE PULLYS WILL BE A NOTCH! YOU WILL NEED A TOOL FOR CLAMPING THE PULLYS! AT THE CRANKSHAFT PULLY WILL BE A NOTCH, MATCH IT UP WITH THE NUMBER "0" ON THE PLASTIC COVER BEHIND THE PULLY!
